In order to study the ship navigation deflection, the motion model of the ship is established on the basis of CFD (computational fluid dynamics), for the numerical calculation and simulation of the motion state of S60 ship model in different water depths. Meanwhile, the calculation result is compared with the experimental data for verification, and it turns out that the two matches well. Afterwards,...
This paper presents an SPH (smoothed particle hydrodynamics) model for numerical simulation of multiphase drop dynamics including liquid drop formation and deformation, coalescence and separation, liquid drop impacting, spreading and splashing. SPH is a Lagrangian, meshfree particle method. It has special advantages in modeling multiphase drop dynamics. Surface tension effects are modeled using a...
With the rapid development of microelectronic technology, thermal behavior of interface structure has become one of the priorities in microelectronic reliability research. Multi-scale coupled analysis has gradually become the main analysis method of the interface heat transferring problem. The coupled method and key modeling technology among MD (Molecular Dynamics), ISE (Interface Stress Element)...
The paper analyzed the channel structure where a manufacturer open up a direct Internet channel retail the product that is in competition with the traditional channel. The paper developed the aggregate demand function under dual channel based on consumer utility, and studied the manufacturer's pricing policies which is to avid the conflict from the traditional retail. Three pricing coordination solutions...
This paper reviews previous studies carried out to investigate the behavior of Corroded RC columns. Current tests used to assess the effects of reinforcement corrosion on the serviceability of RC Columns in the absence of a sustained load were first surmised. Then, analytical and numerical models developed and calibrated with the experimental results to predict the bearing capacity of corroded RC...
A new method on dehydrating mist in gas with high efficiency is presented. Mist in gas can be dehydrated by the bent plate dehydration. Based on the model of steady flow of incompressible Newtonian fluid, the difference equations of flow and pressure field of bent plate dehydration equipment are built. Numerical Solution of vorticity, stream function and pressure are also obtained. The equations are...
